Lobelia plant named ‘Sunlobe Toreho’

ABSTRACT

A new and distinct cultivar of  Lobelia  plant named ‘Sunlobe Toreho’, characterized by its outwardly spreading plant habit; vigorous growth habit; freely branching habit; dense and bushy plant form; freely flowering habit; relatively large white-colored flowers; and good garden performance.

Botanical designation: Lobelia erinus.

Cultivar denomination: ‘SUNLOBE TOREHO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lobeliaplant, botanically known as Lobelia erinus and hereinafter referred toby the name ‘Sunlobe Toreho’.

The new Lobelia plant is a product of a planned breeding programconducted by the Inventor in Higashiomi, Shiga, Japan. The objective ofthe breeding program is to create new outwardly spreading,freely-branching and bushy Lobelia plants with large attractive flowersand good garden performance.

The new Lobelia plant originated from an open-pollination in May, 2007of a proprietary selection of Lobelia erinus identified as code namedANB-LK, not patented, as the female, or seed, parent with an unknownselection of Lobelia erinus as the male, or pollen, parent. The newLobelia plant was discovered and selected by the Inventor as a singleflowering plant within the progeny of the stated open-pollination in acontrolled greenhouse environment in Higashiomi, Shiga, Japan in June,2008.

Asexual reproduction of the Lobelia plant by vegetative cuttings inHigashiomi, Shiga, Japan since April, 2009 has shown that the uniquefeatures of this new Lobelia plant are stable and reproduced true totype in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Lobelia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Sunlobe Toreho’. These characteristicsin combination distinguish ‘Sunlobe Toreho’ as a new and distinctLobelia plant:

-   -   1. Outwardly spreading plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit; dense and bushy plant form.    -   4. Freely flowering habit.    -   5. Relatively large white-colored flowers.    -   6. Good garden performance.

Plants of the new Lobelia differ primarily from plants of the femaleparent selection in flower color as plants of the female parentselection have sky blue-colored flowers with white-colored centers.

Plants of the new Lobelia can be compared to plants of Lobelia erinus‘Lobwhi’, disclosed in U.S. Plant Pat. No. 25,205. In side-by-sidecomparisons conducted in Higashiomi, Shiga, Japan, plants of the newLobelia differed from plants of ‘Lobwhi’ in the followingcharacteristics:

-   -   1. Plants of the new Lobelia were more outwardly spreading than        plants of ‘Lobwhi’.    -   2. Plants of the new Lobelia had larger leaves than plants of        ‘Lobwhi’.    -   3. Plants of the new Lobelia had larger flowers than plants of        ‘Lobwhi’.    -   4. Plants of the new Lobelia had longer pedicels than plants of        ‘Lobwhi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Lobelia plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotographs may differ slightly from the color values cited in thedetailed botanical description which accurately describe the actualcolors of the new Lobelia plant.

The photograph at the top of the sheet comprises a side perspective viewof a typical flowering plant of ‘Sunlobe Toreho’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of atypical flowering plant of ‘Sunlobe Toreho’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following descriptionwere grown in 15-cm containers in an outdoor nursery in Higashiomi,Shiga, Japan and under cultural practices typical of commercial Lobeliaproduction. During the production of the plants, day temperaturesaveraged 23° C. and night temperatures averaged 13° C. Plants were fourmonths old when the photographs and description were taken.
